Biology For The AP Course – James Morris

A Canada lynx (Lynx canadensis) with piercing green eyes seems to be looking directly at you on our cover. The image draws you in, inviting you to ask and answer questions about how life works. The Canada lynx is a visually stunning cat, with its distinctive ear tufts and long hair hanging down from its lower cheeks. Its hind limbs are longer than its front limbs, so its back slopes downward as it hunts in northern forests of North America, searching for prey.

Just from looking at it you can tell it’s a predator, with its sharp eyes, strong limbs, lean body, powerful muscles, and retractable claws. Predation has shaped its form and function over many generations. It has also shaped its prey—the snowshoe hare (Lepus americanus). The interaction of the Canada lynx and snowshoe hare echoes and highlights the themes you will encounter throughout your AP® Biology class.

Evolution has influenced the form and function of all organisms on Earth, and that’s particularly clear when looking at predators and prey. The two have evolved in lockstep, driving each other’s adaptations. Underpinning evolution is the idea of Information Storage and Transmission, which allows organisms to function and pass on traits from generation to generation. None of this would be possible without Energetics—a source of energy fueling the entire process and the ability of organisms to harness this energy to carry out their functions.

And the lynx and hare don’t exist in isolation, but instead are part of an ecosystem that functions as a whole. Thus, Systems Interactions, whether at the scale of a forest or a cell, provides a way to put all the pieces together. While you will approach biology class by class and module by module, don’t forget that these themes are inseparable in nature. The lynx on the cover is there to remind you of the four Big Ideas of AP® Biology and how they work together to sustain life.
